General Description

Slender to moderately robust, often very vigorous root-climbing liane or hemiepiphyte. Shoot system well-differentiated into pendulous, free, lateral flowering branches and adherent shoots; eocaul not observed; seedling with congested leaves closely resembling adult leaves but smaller, becoming progressively larger as shoots elongate. LEAF dark green above, paler below; petiole 1–8 cm, weakly lamina-like, usually considerably shorter than the blade, 1/7 to ? its length, the distal part somewhat to distinctly auriculate, sub-triangular (when short) to subparallel-sided (when longer); blade c. 8–12 × 2–4 cm, ovate-lanceolate to ovate (usually absent from early leaves of a sympodial module), apex not or somewhat acuminate, base mostly rounded; primary lateral veins diverging at 40–85°, intramarginal veins mostly 2 on each side of the midrib, one basal and running to the margin, one from about midway up the blade, running to the tip. INFLORESCENCE solitary, rarely paired, borne on leafless condensed short shoots (these rarely with 1 or 2 reduced blade-bearing leaves) in the axils of usually only the most distal leaves, or less commonly terminal on the leafy shoot, or rarely on older leafless parts of the stem, the short shoots sometimes with scars of previous flowering, subtended by series of cataphylls, the longest and last to c. 3 cm long; peduncle to c. 7 cm long, gradually thickening upwards from from the base more or less evenly throughout its length, slightly curved, deep purple-black. Spathe c. 1 × 2 cm, broadly ovate, emarginate-tipped, mucronulate, reflexed, dark green to dark purple. Spadix sessile, 0.6–1.3 (–1.8) cm diam., spherical, yellow. Flowers c. 1.1 mm diam. (dry), with 6 free tepals and 6 stamens. INFRUCTESCENCE with few to many berries; fruit to 2.5 cm long (fresh), ovoid, ripening deep red; seeds not observed.
